What EY can do for you

Our EY sustainable finance team, including sustainability risk professionals, can help your company develop a sustainability strategy that unlocks new sources of growth, embed nature- and climate-related considerations into strategic planning and risk management, develop a credible climate transition plan, and perform scenario analysis and stress testing.

Furthermore, we leverage our global experiences, tools and capabilities to help your company navigate the complexities of the evolving regulatory landscape, address sustainability-related challenges and unlock new opportunities. Clients benefit from our market-leading sustainability reporting services, informed by sector insights, external benchmarking and leading-edge thought leadership.

Our teams are ready to support you across the full spectrum of sustainability services, represented by the following three pillars: value-led sustainability, accelerated transition and risk management, ESG gap closure.

Shifting sustainability from a reporting- and compliance-focused narrative to a value-driven conversation, engaging with the C-suite to turn sustainability into a business opportunity and helping your company to create and protect value in the short, medium and long term.

Long-term value strategy – We assist you with identifying where and how you differentiate through sustainability and long-term value creation. We then help you formulate a tailored path to sustainability market positioning, integrate sustainability into strategic decision making and align your business functions with sustainable finance goals.
Market scan and peer benchmarking – Together with you and your stakeholders, we co-create benchmarking criteria, conduct research to assess your company against the defined framework, and turn findings into an analysis that shows where you stand in comparison to your peers.
Product and portfolio analysis – We help you enhance your ESG product and portfolio offering by reviewing current products against sustainability frameworks, standards and cross-border regulations, and by turning ambition into a credible, compliant go-to-market strategy.
Supporting your company to accelerate its climate transition journey and helping streamline and execute change projects within the organization, including managing sustainability risks in an integrated form.

Transition planning / climate strategy – We help you integrate your net-zero ambition throughout your business so that it is accountable to these goals, thereby creating value from your long-term, low-carbon position.
Integration of climate and nature risk into risk management – We support your climate and nature risk assessment as well as your strategic planning by incorporating climate and nature risk data into your existing data models and risk management processes.
Stress testing and scenario modelling – By leveraging internal accelerators and our deep expertise, we develop and test climate- and nature-related scenarios against your business model to ensure your strategy is calibrated at the appropriate intensity and in line with regulatory expectations.
Data and technology – By leveraging the EY alliance ecosystem, third-party software market knowledge and EY technology, we help you improve data quality, ensure traceability, accelerate reporting, prepare for assurance readiness and inform strategic decision making.
Activating a roadmap and working with wider stakeholders to accelerate key components of your company’s sustainability strategy.

Non-financial reporting and assurance support – We help you enhance transparency and accountability to stakeholders, as well as assurance to management teams and those charged with governance over the quality of reported ESG and sustainability information. Among other services, we help you with:
Current and future state analysis of sustainability reporting requirements
Performing a robust materiality assessment tailored to international standards (e.g., CSRD, ISSB, GRI)
Gap assessment and actionable insights across mandatory and voluntary reporting frameworks to facilitate timely preparation and compliance
Independent pre-assurance over sustainability reporting (e.g., CSRD, EU Taxonomy, DMA)
Developing sustainability risk and control frameworks to meet strategic, reputational, operational, data, reporting and compliance requirements

Our non-financial reporting and assurance support focus not only on Swiss sustainability reporting and disclosure requirements (e.g., Code of Obligations (CO), Art. 964a-964c and Art. 964j-964l, Ordinance on Climate Disclosures, Sustainable finance self-regulations (AMAS, SBA, SIA)) and requirements of the Swiss Financial Market Supervisory Authority (FINMA) for supervisory companies (e.g., FINMA Circular 2026/1 Nature-related financial risks), but cover also international frameworks (e.g., CSRD/ESRS, ISSB, GRI, SFDR).

Interoperability and connectivity – We provide guidance on how to maximize interoperability among applicable sustainability reporting standards and frameworks in relevant jurisdictions, and on how to enhance connectivity between financial and non-financial reporting.
Green bonds – We help certify green bonds against the Green Bond Principles and/or the Climate Bonds Standard, of which the EY organization is an approved verifier. EY teams can conduct assurance services both before and after the issuance of a green bond and verify the reporting associated with the impacts of projected “green attributes” on a periodic basis.
Role of finance function – We work with your finance function to develop your sustainability strategy. This can be achieved by creating, measuring and communicating long-term value and drawing a connection between non-financial and financing reporting to help manage long-term risks.
Enterprise-wide training – We train your team on sustainable finance, from Board level to all employees, across different business functions.
